Description:
------------
The opcache accesses to invalid address. PHP is running via Apache using mod_fcgid. Php.ini does not
contain any plugins (except opcache). 

Eventlog message:

The description for Event ID 487 from source Zend OPcache cannot be found. Either the component that
raises this event is not installed on your local computer or the installation is corrupted. You can
install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: 

Unable to reattach to base address
Pokus o přístup k nepřípustné adrese. (translation: A try to access to invalid
address)

I have run the attached test script using utility ab.exe:

ab.exe -n 50 -c 3 http://myip/attachedscript.php

This bug is observed in versions 5.6.11-14. Version 5.6.10 seems to work correctly.










Test script:
---------------
<?php
$sec = 3;
echo "waiting $sec s...";

for($i=0; $i < $sec; ++$i) {
	sleep(1);
}

echo "end<br>";
echo "The script has waited for $sec sec";
